CAR-COUPLING.

SPECIFICATION forming part of LettersA Patent No. 551,091, datedDecember 10, 1895. Application iletl October 5,1895. Serial No. 564,792.(Nolnodel.)

To @ZZ whom t may concern:

Be it known that I, VILLIAM P. NYE', a citizen of the United States,residing at Tazewell, in the county of Tazewell and State of Virginia,have invented a new and useful Car-Couplin g, of which the following isa speciiication,

The invention relates to improvements in car-couplings.

The object of the present invention is to improve the construction ofcar-couplings of the Janney type and to provide simple and efficientmeans for limiting` the vertical movement of the draw-heads on eachother when coupled to prevent them from becoming accidentally uncoupled,and also to prevent one of them from dropping to the track in event ofits being pulled out of its fastenings.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a car-couplingconstructed in accordance with this invention. Fig. 2 is a sidee'levation of two draw-heads coupled.

Like numerals of reference indicate corresponding parts in both thefigures of the drawings. I

l designates a drawhead of the J anney type provided with the usualpivoted knuckle 2 and adapted to couple with a corresponding draw-head,as will readily be understood. The draw-head is provided at its knuckleside with an outwardly-projecting horizontal arm 3, located at the topof the draw-head and extending beyond the front thereof when the knuckleis closed. At the other side of the draw-head is arranged a horizontalfiange or ledge 4, located at the bottom of the drawhead and extendingrearward from the front thereof. When two draw heads are coupled, asillustrated in Fig. 2 of the accompanying drawings, the arm 3 of onedrawhead overlaps the other draw-head and is located above the ledge 4Lthereof, whereby stops are provided to limit the vertical movement ofthe draw-heads on each other to Vprevent. them from being thrown out ofengagement by inequalities` of the road and becoming uncoupled, and alsoto prevent a draw-head from dropping upon the track and wrecking thecars in rear of it should it be pulled out of its car and becomedetached therefrom.

It will be apparent that the arm 3 and the flange or ledge 4 permit thenecessary vertical play of the draw-heads and a vertical adj ustmentthereof, so that a light or empty car can couple with a heavy onewithout twisting or straining the couplings. The arm 3 and the flange 4do not interfere with the automatic coupling of the draw-heads,`-andthey may be constructed in any suitable manner and be formed integralwith or be secured to the draw-heads.

It will be seen that the safety device for carcouplings of the .Ianneytype and analogous ones is exceedingly simple and inexpensive inconstruction, that it is positive and relie able in operation, and thatwhile preventing absolutely two draw-heads from becoming un coupled ordisengaged through vertical moveyment on each other it permits a limitedvertical movement or play to avoid straining the couplings or theirconnections with the cars. It will also be apparent that it does notinterfere with the free use of the coupler, and the efficiency of thelatter is nowise impaired, and the operations of coupling and uncouplingmay be performed with as great facility and convenience as though thesafety device were not applied.

Changes in the form, proportion, and minor details of construction maybe lresorted to without departing from the principle or sacrificing anyadvantages of the invention. What I claim isl. A car coupling of theJanney type or the like provided at one side of the draw-head with aforwardly projecting arm, and having at the opposite side a ledge orflange, whereby, when two draw-heads are coupled, the iianges and thearms will lie in the same vertical plane and form stops to limit thevertical movement of the draw-heads on each other and prevent them frombecoming separated, substantially as described.

2. A draw-head of the .Ianney type provided at its knuckle side at itstop with an outwardly extending horizontal arm, and having at its otherside at its bottom, a horizontal flange IOO or ledge extending rearwardfrom the front my own I have hereto affixed my signature in of thedraw-head, said arm being of a length the presence of two Witnesses. toproject beyond the draw-head, when two draw-heads are coupled, and tolie above the VILLAM P. NYE. adjacent flange or ledge, substantially alsand \Vit11esses: for the purpose described. JOHN Il. SIGGERS,

In testimony that I Claim the foregoing as HAROLD II. SIMMS.
